In comparison, the published short circuit current for a single cell is 6,150A. Consider a 2500 Ah cell having a published internal resistance of 0.049mΩ. This battery has 240 cells and the external circuit has a resistance if 21mΩ. The short circuit current is estimated to be:-
For large batteries such as those used in Power Stations, short circuit currents may exceed 40k amperes. Even when the battery is not fully charged, the short circuit current is very similar to the published value because the internal resistance does not vary substantially until the cell approaches fully discharged.
The short circuit current of industrial standby batteries may be extremely high, even when the nominal characteristics do not suggest this. In a real live situation, even with small batteries, it is not unusual for currents to be several thousand amperes.
The trend observed in the module's response to a local cell short circuit aligns with that of a single cell short circuit. Thus, five critical parameters (peak current, duration, peak temperature, maximum voltage drop, and release current) were extracted and compared.
The voltage of Cell 02 dips to about 0 V, and the ESC current diminishes to 0 A as the short circuit branch current equals that of Branch 1. The voltage of the remaining cells in Branch 1 elevates to over 4.4 V, while the cells in Branch 2 exhibit a voltage below 3.5 V, as demonstrated in Fig. 19 (C) and (D).
The short circuit current is then calculated by ohms law where 2.00V may be used in the calculation. Some manufacturers may use the typical open circuit voltage of the cell which will largely be dependent upon the specific gravity of the cell. Values between 2.05V and 2.15V may be used. HOW DO WE USE THE VALUES OBTAINED?
